The common house spider is harmless and is usually the spider that people most often encounter in their homes. The compact cobwebs that it creates are often a nuisance. Because of it’s brown coloration, it is often mistaken for brown recluse spiders.
The house spider build cobwebs in random locations where it is likely for them to catch prey. It they do not catch prey, they abandon that web and build another one in a different location.
House spiders feed on flies, mosquitoes, ants and other small insects.
House spiders are nuisance pests but little threat to humans.
To prevent common house spiders from entering the home, seal cracks and use screens on windows and doors. Use a vacuum to remove adults, egg sacs and webs. If a broom is used, adults usually escape.
